3D Sound and Prizma Performance Mutes

Wiessmeyer & Son mutes are the harmonious union of traditional acoustic concepts and today’s state-of-the-art technologies and materials. The unique design of the various models offer many different muting effects while allowing the tonal nuance and individual character of the instrument to remain. Along with our customers we believe these are the very best mutes available on the market today. 

Our mutes are semi-hollow and feature an internal structure that approximates the acoustic qualities of rigid organic materials such as natural wood, eliminating the dull/hollow sound associated with solid rubber and rigid metal mutes.


Our original 3DS mutes emphasize sound quality over all else and produce a slightly darker, nuanced tone than our Prizma series. Featuring wider string and bridge tolerances they are designed to hold on the string windings where they have minimal impact on behind-bridge harmonics. They feature an irregular internal matrix that mutes while allowing overtones to pass through the bridge. This gives our mutes a unique and colorful sound quality not found in any other mute on the market.

Prizma mutes are lighter and more flexible than our original 3D Sound mutes with different tolerances around the strings and bridge. They are built for speed yet allow the tonal nuance and individual character of the instrument remain. Prizma mutes temper the volume of any violin, viola or cello while maintaining the warmth and color of the instrument. 3D-printing, 14 base colors, and some nifty algorithms make each Prizma mute we craft a distinctive piece as unique as the musicians who play them!

Prizma Dual Tone Mutes are designed for players interested in expanding their instrument’s acoustic repertoire.

  • The mute sounds different because it filters out fewer overtones during volume reduction. We accomplish this feat using 3D-printing magic and material science
  • Place it on-top of the bridge for a pianissimo that filters out higher and lower overtones while preserving mid-range overtones
  • Pinch it up against the bridge for a mezzo piano that evenly filters half of the bridge
Dual Tone Trio

Viol Trio

Prizma viols are based on the original Kaston mutes patented in 1971. Our viols offer several advantages over the mass-produced rubber mutes synonymous with an entry-level student mute. Designed to replicate the sound popular with 1950’s recording artists when this mute was still hand-made from wood, leather, and glue.

  • Our mutes sound better because they filter out fewer overtones during volume reduction. We accomplish this feat using 3D-printing magic and material science
  • They don’t buzz or rattle on the string(s)
  • They fit anywhere on the bridge
  • Produce a light, playful mezzo piano
